Thomas - 4425 Traceable Workhorse Thermometer, Type K Thermocouple, -58 to 2372 Degree F, -50 to 1300 Degree C, Probe Range (Supplied with Unit) -45 to 230 Degree C, Accepts All Type K Probes

The Thomas Traceable Workhorse thermometer measures temperature from -50 to 1300 degrees C (-58 to 2372 degrees F), with an accuracy of + or - 1 degree C, + or - 75%. The 3.125"-long stick probe is 0.125 inches in diameter and is attached to the base with a 40" cable. The recessed front panel has an adjustable offset function that enables the unit to be calibrated to an in-house standard or a particular sensor for increased accuracy. The thermometer is traceable to National Institute of Standards and Technology standards, indicating that it is calibrated to International Organization for Standardization (ISO) 17025 levels. This Thomas thermometer is used to monitor temperature in high-temperature industrial settings. Probe range (supplied with unit) -45 to 230°C; 3¼" stem, 0.2" stem dia, 30" cable; accepts all Type K probes Specifications -------------- Power source (1) 9V battery Temperature range -50 to 1300 degrees C (-58 to 2372 degrees F) Temperature accuracy + or - 1 degree C + or - 75% Resolution 0.1 degree C (from -50 to 200 degrees C), 1 degree C outside this range Standard met International Organization for Standardization (ISO) 17025 Weight 6 oz. Dimensions, probe (H x diameter) 2.125 x 0.125 inches Dimensions, base (H x W x D) 5.5 x 2.75 x 1.25 inches H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. Digital thermocouple thermometers measure the temperature of air, liquids, or surfaces. They may measure temperature in Celsius, Fahrenheit, or both. Thermocouple thermometers are composed of two conductors of different metals, usually alloys of the same metal, which touch at the sensor end of the thermometer. The difference in conductivity between the two metal pieces produces a voltage flow between the sensor end and the open end of each conductor, which can be used to determine the temperature. Different alloys are used for different temperature ranges. Thermocouple thermometers are used in applications that require a large temperature range and do not require a high degree of accuracy. These thermometers are used in kilns, turbine exhaust systems, and furnaces. Thomas Scientific manufactures lab supplies, equipment, s, and instruments for scientific research. It is a registered contractor for the United States Federal Government. The company was founded in 1899 and is headquartered in Philadelphia, PA.
